Question Ron, how much room do you have under your waterline? I only had enough room for a 14 inch prop and a 1 inch cross section nozzle, and I had to make some real changes in my rudder... Room is the problem.. Dave K
PS... I have some pictures in the album section.

Dave,
You made a great point about weight, a large mass in motion will be less sensitive to extracting a regen value.
I'll throw out an idea, but will not try to explain in too much detail, as I can never say things just right.
A two function design using the nozzle you mention, a small high speed power prop inside the nozzle and the nozzle turns as a large regen unit, having several blades on the outside diameter that can be feathered for least resistance when the power prop is in use, then feathered for maximum regen when being powered by wind or current movment.
So basiclly a two prop system. Massive torque and high speed power seem to always be on opposite ends of where they are needed.
Ron
